finite intersection

Hey, I am really stuck on a question so if anyone can help me I would be very grateful.

Show that the set of finite unions of closed intervals

in

has the f.i.p.

I know that for a collection of sets to have the finite intersection property means that each nonempty finite sub-collection of these sets has a nonempty intersection.

I really need help on this question, analysis is killing me.

Thanks in advance for any help.

Re: finite intersection

I'm not entirely sure what your set actually is. How are the x_i and y_i defined?
